Nasty Plot

Nasty Plot is a Dark type move that simulates the user thinking nasty thoughts, hence the name. When a Pokémon uses this move, its Special Atk will sharply rise (go up by 2 stages). Pichu is the only Pokémon in its evolution system that can learn the move Nasty Plot. After using this move on 3 separate occasions, the user's Sp. Atk will reach the maximum, and the move can no longer be used.
